One of my favorite fight scenes from the franchise was Power Rangers in Space, episode 26: The Secret of the Locket. It featured an extremely intense battle between Andros and Ecliptor, and the best of all, a villain VS villain fight scene.

Another would be the Titanium Ranger introduction arc in Power Rangers Lightspeed Rescue, particularly the fight between Titanium VS Pink Ranger, as well as when Titanium Ranger eventually becomes good and beats the three monsters of the week. While obviously Titanium Ranger is a fan favorite because he's the first US exclusive Ranger, the fight scenes really helped making him look badass.

When it comes to Power Rangers personally I really prefer the action directing from In Space to Wild Force, imo the best era of Power Rangers when it comes to everything. My gripe with Disney seasons is that they become too obnoxious especially when blasters are firing but only hits the ground because they only have sparks on grounds.

And that is why Sentai's fight scenes are a lot different, because they have access and experience of sparks on bodies, so I guess that is what you meant by fights being more brutal. It does help that Japanese children programs are a lot different than American children programs, where Japanese violence have a bit more freedom, and Power Rangers often have to become childish because American (and New Zealand) parents kept complaining that the show is too violent.
